Answer:
I believe the answer is D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
She can make 10 dresses if you split the number line into 20 parts and find 2/5. Therefore, it would then be grouped into 10 parts, each part 2/5ths of a yard.
Answer:
7.9 X 10^3
standard form means it has to between 1 and 10
If you divide on a calculator, you get 4.468208092, so I would say the answer is 4.4, since the number after 4 is 6, which is more than 5, I round to the 4. Hope this helps!
Aye Sir!
Answer:
x = -8
Step-by-step explanation:
-2.5x - 2 = 18.
Add 2 to both sides.
-2.5x = 20.
Divide both sides by -2.5.
x = -8
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775
